SUMMARY

This study examines seasonal variations and controlling factors in CO2 exchange in a secondary tropical peat swamp forest in Sarawak, Malaysia using the eddy covariance method. Net ecosystem CO2 exchange (NEE) was observed to be negative throughout the year, indicating that the ecosystem acted as a net carbon sink. However, it was observed that there was a decrease in CO2 uptake during the dry season compared to the wet season in which there was a decrease in daytime uptake while night time emission remained constant. The diurnal NEE pattern at this study site was consistent with that of other studies in the Amazon and other peatlands.
